The present invention relates to a cooling system forrailway cars andthe like, whereby t e process of mechanical refrigeration is appliedmost efficiently in cooling the atmosphere of the car and whereby inconnection therewith or independently a continuous sup-- ply of coldwater uncontaminated by contact with ice and colder than can be obtainedby the use of ice is maintained. In the accompanying' drawings I haveillustrated a cooling apparatus embodying the features of my inventionin the preferred form and also showing certain modifications thereof.

In the drawings: v Figure l is a'front elevation of a stand or casing,enclosing the compressor condenser coil, water cooling compartment andother elements and details of the apparatus.

Serial in, $70,012.

which is supported a cooling compartment 2, enclosing the water coolingcontainer shown in the form of a water pipe 3, referred to herein as astand ipe of comparatively large diameter, the ext which pipe at 4 formsa tank for cold water to which thecooling effect of the apparatus isdirectly applied. This pipe 3 in the form of the invention shown issupplied with water from a tank5, carried by the coach in 56 anyconvenient location, compressed air and gravity feed forcing the waterto points where needed, in this case itbeing' supported in the top ofthe car 23, from\ which the pipe 3 depends, extending downwardly intothe com- 60 partment 2 as already described.

The pedestal or upright casing 1,'in the preferred form of theinvention, encloses a condenser coil 6, shown at the bottom'in'Figure 1. This is for cooling the compressed re m gerant, which isreferabl sulphur di.- I

oxide though any pre erred re rigerant may be used. This c011 issupplied with compressed refrigerant from thecom'presser 8 ,driven byany suitable motor, the coil being cooled in any suitable manner asby'means of av draft of air entering in the preferred form, Figure 1',at the bottom from beneath the car through the floor 9 by way of anopen.- ing 10, registerin caTsing-1,'t'he air eing led upwardl by aslight vacuum which may be created COD- 'necting the casing l by meansof a pipe 11 connected to the-casin with one ofthe venti the car, or thedraft may be created in any suitable -manner.: It ;will be easilyunderabove the compressor stood that the casing 1' acts as an airpassage and that when the car is 'inmotion .the air 1 is suckedontattheyentilators creating a draft through-the coil-byway of pi e 11.

The-portion of thesystem containingt e re- I frigerant is"thushermetically sealed an separated from the interiorof the car, avoiding any possibility that in case of accident eme lower end portion of60- with the bottoin of the 76' ators 12 at the top of -80 J or from anyother-cause, the refrigerant,

c of the fitting20.

which is considered harmful, may not escape intothe passengerscompartment. In case of leakage, the vapor is carried outside with thecooling air, p

Referring now to Figures 1, 4 and 7, the refrigerant which is compressedby the com- 'pressor8 and cooled in the coil 6', is led up-- wardly fromcoil. 6 by a pipe 14 through the reducing valve 13 to a coil 15, WlllChis shown as inside the water cooling compartment 2 and preferablyencircles a brine or holdover tank 16 which, in turn, encloses the lowerrtion'4 of the coldrwater pipe which is chil ed in a manner to bedescribed furnishing ice water'for drinking. This coil 15 is referablyof the helical conduit construction illustrated in detail in Figures and9, consisting of an outer tubular cylindrical casing 17 a helical shell18 enclosed within the casing 17 and in contact or nearly in contacttherewith providing a helical assage 19 immediately within the casing17, t rough its periphery, which, in this instance, is utilized for therefrigerant which is introduced directly thereinto from the pipe 14 byway member 21a helical ora similar corrugated passage '24, which isenclosed between the central tubular member 21 described as for.carrying the refrigerant and the helical conduit or' passage 19 on theoutside, also described as: carrying the refrigerant, though itnydofthese'passages may be otherwise .uti-

ize v The coil is connected at its lower end by fittings25 and .26 to bedescribed, or in any suitable mannerto an air pipe 27, s'ee also Figure7 ,,which as shown preferably leads alon the floor of the cardistributing cooled air ,t rough a seriesof pipe connections al thoughit maybe located within the car in any suitable manner, this piple beinshown as perforated at 28,-though t e per orationsare not regarded as anessential feature.

The coil 15, as already described, extends upwardly about thebrine' tank16 and terminates at the top, as best illustrated in Figure 5 in theinlet air pipe 28, whereby air is intro-1 duced either b a fan, suctioilorv pressure from any suita le source as outside the car.

. At the top the outer helicalconduit 19' conto a cross or four wayfitting 31and the taining refrigerant is. connected by a fitting innercentral tubular member 21 is likewise connected theretojby a fitting32,-the return pipe 34 for the refrigerant from the cooling pipe 33 atthe top 0 the car bBlHgllkGWISG connected to said cross fitting 31 by afitting 35. The remaining connection of said cross fitting 31 isconnected by a fittlng 36 to a cooling coil 37 within the brine tank 16and surrounding the standpipe, 4 for the coolingwater which coil 16leads the refrigerant to a return pi' e38, which is connected to thesuction o the compressor. In this connection it will be understood thatbrine is used as designating *any nonfreezing. liquid or solution. v

As a means for supplying air, the inlet air pipe 28 to the air coolingcoil'15 is connected to the ventilator 12 and provided with a blower ofair pump 40, driven by a suitable electric motor, this equi ment beingdiagrammaticaligure 7 .The air from the ly indicated in cooling coil 16is released from the perfprated pipe 27 along the .bottom of the bar or1n any convenient location, perforations 28 being merely illustrative.

To provide further cooling of the atmosphere. of the car, refrigerantis, led from the 1 pipe 14 by way of a pipe 41 upwardly to the top ofthe car, being there introduced into any suitable cooling passage, asthe outside helical passage 42 of a conduit 43, which may be constructedsomewhat after the -manner of the conduit 15, the outer casing 17 beingpreferably omitted. This pi e has an inner conduit 44 which may be usedor brine, which begins also known as'a holdover pipe in that it retainsthe cooling effect after the refrigerant has been released, drawn ofl orbecome inactive for any reason.

The refrigerant from the pipe 41 is introduced into the helical passage42-of the combined conduit 43 in the. form of the lnvention shown atthetop center of the car, although at the center of'the car'beingplugged at this point as indicated at 45. x This brine pipe is Hm thislocation is not essential, by way of a reducing valve 46 shown at this.point, the .re-

frigerant flows in contact with the brine for the full length of thepipe which as shown is half the carlength. The return pipe 34 of the.coil plpe 33,i's connected atthe end opposite to the point where therefrigerant-is intro-n duped from the reducing valve 46, by way of thefitting 31. In t from the overhead cooling pipe 33 is combined in thewater cooling coil 37 already described.

In theform of the invention shown, par- 35 to the cross or four wayfitting is fitting the refrigerant from the three passages in the aircooling coil 15 and ticularly in Figure 4, rovisiortis made forutilizing the inside 0 ,the cooler casing 2,

aside from what is occupied by the coils andthe water cooler'to holdairwashing water for cleaning the airintroduced by way ofthe'coil 15. Tothis end the fitting 25 already referred.

to is shown in theform of a norri'et urn valve to prevent theentrance'of water into the air vided in the form of a three way valvewhich may be turned so as to prevent the cooled air from the coilfrompassing directly to the pipe 27 and so as to dlscharge this air fromthe coil 15 into the wash water indicated by reference character 43. Theair thus introduced into the wash water passes upwardly into the air. sate 47 ,and hence by way of the bypass 48 bach to the pipe 27 at a pointbeyond the three way valve 26 whence it passes to the perforated portionof the pipe 27 shown in .Figure 7. The bypass 48 is alsoshown asprovided with a three way valve 49 above the compartment 2' and anupwardly disposed open elbow 50 connected to the 'three way valve sothat by turning the valve 49 the al-- bow 5'0 may be connected to thecompartment end 51 of the bypass 48, whereby the elbow 50 may beutilized for introducing water into the compartment.

As will be noted in Figure 7, it is proposed to provide a constructioncorresponding to that shown in Figures 1 and 4 at each end of the car,the cooling pipes 33 and 27 being in two parts or separate unit'sconnected to the -respective cooling apparatus at the respective ends ofthe car so that there are two reducing valves 46 at the center and twopipes 27 and 33-extending from each end toward the center, though thisarrangement is not essential to the operation'of the invention.

Figure 6 shows a water cooling compartment 55 adapted to cooperatewith acasing or pedestal 1,- as shown in Figure 1, or any suitable pedestal asthat shown in Figure 2 to be later described. This com artment isconnected to the condenser coll 6 by a pipe 54 and to the compressor bya return pipe 58.

This condenser pipe 54 is provided with a pressure reducing valve 56from which the expanded refrigerant is led'directly to a water coolingcoil 56 or any suitable means to bring the refrigerant" into heatexchanging relation withthe water. As shown, the coil 57 encircles thewater standpipe 59, being connected at its lower end to the return pipe58', it being understoodv that this cooler may be combined in anysuitable manner, for ex-' ample, as shown in Figure 7, with any or allof the air cooling features therein disclosed.

This compartment is shown as containing a brine tank 60in which the coil57 is immersed, the brine tank in turn surrounding a cold water tank 59.This compartment 55 is further shown as intended to be utilized as-a'nemergency ice chamber to supply the cooled drinking water in case offailure of the refrigerator system for any reason. In this form of'the.invention, instead. of the standpipe 3 being integral and continuouswith the cold water tank 4, as shown in Figure 4, there is aseparatecoldwater tank 59 connected to the standpipe 3 by-water'connect'ion which,in the form of the invention shown, serves as leading from t therefrigerator coil 57 and immersed in the brine in the tank 60. Thisconnection 85 as shown extends downwardly from the'standpipe 3 throughthe brine in the tank 60 and 1s coiled' about the tank 59, the coil alsobe-.'

ing immersed in the brine and extending upwardly. As shown, the up erportion of' this water coil 86 is wound a out the upper h part of therefrigerator coil 57 at 87, the arrangement being preferably of thetype' shown in Figure 3. This portion of the coil 87 which is woundabout the refrigerator coil as shown, is then connected at 88 to the toof the cold watertank 59. -It will be un erstood that in'the operationofthis form of the invention, the water passing from the pipe 3- tov thetank 59 is ,cooledlmmediately, the chilled water entering the tank, bits greater specific gravity dropping immediately to the bottomIof thetank where it enters the pipe 89 leading to the cold water faucet'65. Inthis way, the lag incident to the production of cold water when therefrigerator system is first connected up at the time the train isstarted is overcome and cold water is made instantaneously available.

To overcome the'possible objection to the use of mechanical refristation in assenger cars on account of'the c ance that t e refrigerantmay escape in case of accident, and have a harmful effect onthepassengers, the apparatus is shown as provided in each instance inthe water cooling compartments 2 and 55, and also in the casing 1containing the compressor and condenser .coil 6, with a fragile orfrangible container62, which may contain an antidote, for therefrigerant. Where S0 is used as a refrigerant, the bottle may containammonia and where ammonia is used as a refrigerant the bottle maycontain any suitable acid, volatile or otherwise. This contai neri isnormally sealed and is. carefully desi ed of just the right resistanceto shoc so that it is broken and the contents released when and normallyonly when the refrigerating system is punctured. In Figure 8, which Isasection on the lill ilig 88 of Figure 7-, the overhead cooling'pipes 33are shown as supported over a trough 63 ins to catch'thecondensedmoisture and prevent I dripping, and in each instance the watercool er is shown as lprovided with a water pipe 64 e standpipe4 or 59 toa spigot 65 arranged in a suitable niche 66 in the compartmentcover 67.In Figure lthere'is an aperture 68 for the introduction of used cupswhich pass downwardly through a'pipe 69.to a suitable receptacle notshown'and reference character 70 indicates asuitable container for newcupsF Figure"2 shows a slightly modified construction of' pedestal whichis slightly-raised from the floor and the floor 9 being closed be 130neath the pedestal, and air openin 7 2 being provided at the bottomabove the oor. I This pedestal is shown as provided with air dis.-

he operation of the apparatus has been the coil 37 which surrounds thecooling water container 4, within the brine tank 16, the

1 coil 37 being immersed in the brine, asha's been explained. Thedrinking water is cooled by the coil 37, the cold air su ply being assedthrough the passage 24 of the coil 15 etween the inneran'd outer streamsof refrigerant. In this'way chilled water is supplied to the cold waterspigot 65 and chilled" or cold air to the perforated pipe 27 in the car,the air to be thus cooled and released being propelled in any suitablemanner as by means of a blower or pump drawing air from the ventilator-It will be understoed thatthe fitting 36 combines the return refri erantfrom the contact cooling pipe 33 an from the inside and outside passagesof the coil15, the refrigerant from all three fsources being passedthrough the coil 37 -pipe'27 by .way of pi e 48and three way valvesurrounding the "cooling'water container 4 as described: The arrangementof coils 15 and 33 is particularly advantageous in that it tends toconserve the refrigerating effect and ap ly the surplus left fromcooling the air to the drinking water.

Figure 6 illustrates a water cooler which is like that shown in Figure4, except that the compartment 55 .corresponding'to the compartment 2,is used for ice for cooling in an emergency instead of for airwashing'water, andthis water cooler is not directly connected to the aircooling and cool air supplying elements described particularly inconnection with Figures 1, 4 and 7 r I have thus described specificallyand in detail a water and air coohng apparatus for railway cars and thelike, the description beingzspecific and in detail in order that themanner of construct-ing, operating and using the apparatus may e fullyunderstood.
